CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of the filing date of U.S. Provisional Patent Application No. 60/667,261 filed Apr. 1, 2005, the disclosure of which is hereby incorporated herein by reference.

BACKGROUND OF THE INVENTION

When packaging and displaying various products, such as candy, the object is often to provide an appealing visual display container, while also functioning as a storage or shipping container for the product. One such prior art display container being used for candy is shown in FIGS. 1-4. This display container includes a transparent container 100 having an inwardly extending circular protrusion 102 at its bottom end and a cover 104 having an outwardly extending corresponding circular protrusion 106 at its top end.

The prior art containers provide a visually appealing display for candies and are also vertically stackable with each other. However, these containers do not fixedly interlock with each other when they are stacked due to the circular design of the protrusions, and therefore, they easily move and/or rotate during shipping or storage, which can result in damage to the candy inside. These known containers are generally unstable when stacked for shipment or storage. Accordingly, these containers often require that they be packaged in a sealed cardboard box for shipping in order to prevent any damage to the products disposed therein during shipping.

Thus, there is an unsolved need in the art for display containers which overcome the problems associated with these known containers, such as those noted hereinabove that may occur during shipping and storage.

SUMMARY OF THE INVENTION

The present invention generally relates to a display container having a cover. In accordance with one embodiment, a container includes a shell having a bottom with an inwardly extending non-circular protrusion and an open top; and a cover for the open top of the shell having an outwardly extending non-circular protrusion.

Still more particularly, the invention relates to a container having a closed bottom section with an inwardly extending protrusion, and interconnected side walls connected to the bottom section; and a cover for the display container having a closed top section with an outwardly extending protrusion, and interconnected side walls connected to the top section. The outward protrusion located at the top of the container cover will interlock with the inward protrusion in the bottom of the adjacent container when the containers are stacked on top of each other making them substantially immovable and thus less susceptible to damage during shipping and storage.

It is one aspect of the present invention to provide a container and cover combination comprising a container having a bottom with an inwardly extending non-circular protrusion and an open top; and a cover for said open top of said container having an outwardly extending non-circular protrusion, wherein said protrusion of said container and said protrusion of said cover are configured to interlock with each other when nested within each other to prevent rotation therebetween.

It is yet another aspect of the present invention to provide a container and cover combination comprising a container having a bottom with an inwardly extending opening and an open top, and a cover for said open top of said container, said cover having an outwardly extending projection, said projection releasably nestable within said opening when said container is supported on said cover, said opening and said projection each having a shape which prevents rotation of said cover relative to said container when said projection is nested within said opening.

It is also an object of the display container disclosed herein to provide a container with cover for displaying various products in an attractive and reliable manner while also discouraging the unintentional discharge of or damage to the products disposed therein during shipping and storage.

The display container of the present invention preferably includes a transparent container with a closed bottom section with an inwardly extending non-circular protrusion; and a cover for the container having a closed top section with an outwardly extending correspondingly shaped non-circular protrusion.

The preferred display containers of the present invention includes polygonal shaped protrusions at the top of the cover and at the bottom of the container so that they can be interlocked when the containers are stacked on top of each other.

DETAILED DESCRIPTION OF THE INVENTION

In describing the preferred embodiments of the present invention, specific terminology will be resorted to for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and is understood that each specific term includes all technical equivalence which operate in a similar manner to accomplish the same purpose.

Referring first to FIGS. 5-8, there is shown, according to one embodiment of the invention, a transparent container 1 with a closed bottom section 3 with an inwardly extending non-circular protrusion 5 or opening, and interconnected side walls 10 connected to the bottom section 3 forming an open top container. The cover 20 of the display container 1 has a closed top section 23 with an outwardly extending non-circular protrusion 30 or projection surrounded by a recess 25, and interconnected side walls 35 connected to the top section 23. The protrusion 30 extends above the top section 23. The top section 23 of the cover 20 and the bottom section 3 of the container 1 are essentially flat, so that they are in contact when stacked on top of each other, either during shipment or when in use as described hereinafter. The container 1 and cover 20 may be made of any suitable material. The preferred material is plastic and can be transparent or of any color desired. Preferably the container 1 is transparent to allow the product with the container to be visible to the consumer. The cover 20 may also be of any color or transparent.

It is to be understood that although the container 1 has been shown as having sidewalls 10, the container may be of any shape such as round, oval, polygonal, square, or the like. The cover 20 may also be of other shapes, preferably being the same shape as the container 1.

The shape of the outwardly extending protrusion 30 of the cover 20 and the inwardly extending protrusion 5 of the display container 1 can be of any angular or non-circular shape that would prevent the containers from rotating when stacked on top of each other. For example, the shape of the protrusions may be octagonal, triangular, rectangular, trapezoidal, polygonal, +sign, − sign or any other such shape. As shown in FIGS. 8-9, the preferred shape of the outwardly extending protrusion 30 of the cover 20 and the inwardly extending protrusion 5 of the display container 1 is polygonal. In this regard, the protrusions 5 and 30 will nest inside one another to prevent the stacked containers 1 from rotating relative to one another.

In addition, the shape of the outwardly extending protrusion 30 of the cover 20 and the inwardly extending protrusion 5 of the display container 1 may be of different shapes and sizes with respect to each other as long as they are configured to interlock with each other when nested within each other to prevent rotation. For example, the shape of the outwardly extending protrusion 30 of the cover 20 may be a + sign, and the shape of the inwardly extending protrusion 5 of the display container 1 may be a − sign.

Moreover, the outwardly extending protrusion 30 of the cover 20 and the inwardly extending protrusion 5 of the display container 1 are sized so that when they are nested in each other, they do not become stuck in each other.

As shown in FIGS. 9-10, the cover 20 can be removably fixed on the top of the container 1. In order to obtain a good seal, the cover 20 has at least one outward peripheral edge 51 as shown in FIG. 9, which can grip over at least one outward peripheral edge 56 of the container 1 as shown in FIG. 10.

As shown in FIGS. 11 and 12, the cover 20 may include labels 61 attached to the side walls 35 of the cover 20. The labels 61 may contain any texts or graphics that a user would like to incorporate in order to make the display container more attractive and appealing, including product identification and advertising labels.

In the embodiment illustrated in FIG. 12, MilkyWay® candy bars 60 are housed in the display container 1. However, the present invention is not limited to storing only candy products, but any other products desired, such as hard candy, pencils, key chains, novelty items, etc. Because the display containers of the present invention interlock and do not rotate when stacked on top of each other, the display containers can be used as reliable storage and shipping containers. A plurality of stacked containers 1 are shown in FIG. 13. Because the display containers also provide reliable shipping containers, the display containers filled with fragile products do not need to be packaged in a sealed cardboard box. Instead, a large volume of display containers of the present invention filled with fragile products can be shipped to a destination on a pellet with shrink-wrap around them.

In use of the container 1 as shown in FIG. 14, the cover 20 may be removed and used as a supporting base for the shell 12. In this regard, the top section 23 of the cover 20 will support the bottom section 3 of the container, with the protrusions 5 and 30 nested within one another thereby preventing rotation of the container when in display mode for sell the contained product to the consumer.

As these and other variations and combinations of the features discussed above can be utilized without departing from the present invention as defined by the claims, the foregoing description of the preferred embodiments should be taken by way of illustration rather than by way of limitation of the invention as defined by the claims.
